Pollution og miljøløsninger er en engelsk-opgave fra 2007 til 9. klasse, afleveret til karakteren 4. Fylder 1 side (336 ord, ca. 1 min. læsning) og blev publiceret 14. januar 2010.

Redegørelse for global pollution, herunder biludstødning og drivhusgasser, samt deres indvirkning på ozonlaget og global opvarmning. Opgaven beskriver Kyoto-protokollen og præsenterer forskellige løsninger for at forbedre miljøet, såsom solceller, vindmøller, brintbiler og elbiler. Den giver også tips til dagligdags handlinger for at reducere forurening.

There is a lot of pollution in the world. Pollution can be car exhaust, trash we just drop out in the nature or a simple thing as a hairspray can manage co2 out. Pollution isn’t good for the environment; it can destroy the ozone layer. The ozone layer is 15 km to 35 km above Earth's surface, and if we keep polluting the ozone layer, there will be a greenhouse effect. The green house effect will might destroy the earth in the future, because of the global warming, and then Antarctic will melt and flood over Europe.

The Kyoto Protocol is an arrange to reduce leak of co2 and greenhouse gases. In June 2007 there have been a total of 172 countries that have agreed and signed under to reduce leak of co2.

Those countries there leak most co2 is:

Bahrain: 23,68

USA: 19,73

Canada: 17,24

Ton per inhabitant.

How can we improve our environment. There have been a lot of solutions, how we can improve our environment. One of the ideas is to use solar cell, when the sun shine on the solar cell, there be cultured energy. Another method to protect our environment is to use windmills. It’s a machine designed to convert the energy of the wind into more useful forms using rotating blades, at the same time windmills can grind grains. They have been tested to use hydrogen in cars instead of gasoline, and the hydrogen will almost leak no co2 out. Battery electric cars is a car with no engine, they have been replaced with a battery instead of the engine. There is no pollution, and you only need to pay for the batteries, so they can be charged.
